Definitions

  • the outer peripheral surface of the sleeve can be cylindrical. However, it is particularly expedient if the outer circumferential surface of the sleeve widens conically towards its lower end face. This configuration has the advantage that loosened soil located in the area of the screw rib easily reaches the conical circumferential surface of the sleeve when the drill is pulled up and is pressed by it against the borehole wall and compacted therein.
  • 10 denotes the lower end of an earth auger which is used to produce an in-situ concrete displacement pile.
  • the earth drill 10 consists of a cylindrical, tubular shaft 11, which carries at its lower end a drill bit 12 which closes the cylindrical interior 13 of the drill 10 and is releasably fastened to the lower end of the shaft 11 with a claw closure (not shown).
  • the drill bit 12 consists of a substantially flat plate 14, which on its Underside carries a soil loosening strip 15 extending across the plate 14, which is a straight strip in the exemplary embodiment shown in FIG. 5 and is shaped according to an S in the exemplary embodiment shown in FIG. 6.
  • the shaft 11 of the earth auger 10 carries on its outer circumference a screw rib 16 which, in the exemplary embodiments shown, has only two screw turns 17 and 18, but can also be designed with more screw turns.
  • the screw rib is welded onto the outer circumferential surface 19 of the shaft 11 in the form of a narrow steel band and is designed in such a way that the pitch of the upper screw pitch 18 is greater than the pitch of the lower screw pitch.
  • the upper screw path 18 ends at a displacement body 20 which is arranged at a distance from the lower end 11a of the shaft 11, surrounds it concentrically and can also be made in one piece with the shaft.
  • the displacement body consists of an upwardly widening, smooth-walled conical part 21 and a smooth-walled cylindrical part 22, the outer diameter D of which is as large as the outer diameter S of the screw rib 16.
  • the cuff has 23 on its lower end face 24 two projecting claws 25, which serve to loosen the soil when the drill is brought down.
  • the cuff 23 also has at least one bottom entry opening 26 on its lower end face 24, into which a partial screw surface 27 opens, which extends from the upper end face 28 of the cuff 23 and to which the lower screw thread 17 of the screw rib 16 adjoins upwards.
